# Test Implementation Patterns
## Reference Selection
| Test Type | Reference | When to Use |
|-----------|-----------|-------------|
| **Unit / Integration** | [references/frontend.md](references/frontend.md) | Implementing React component tests with the repository's configured runner and network mocking layer |
| **E2E** | [references/e2e.md](references/e2e.md) | Implementing browser-level E2E tests in the existing harness, or Playwright when the approved work introduces a harness |
## Common Principles
### AAA Structure
All tests follow **Arrange-Act-Assert**:
- **Arrange**: Set up preconditions and inputs
- **Act**: Execute the behavior under test
- **Assert**: Verify the expected outcome
### Test Independence
- Each test runs independently without depending on other tests
- No shared mutable state between tests
- Deterministic execution — mock random and time dependencies
### Naming
- Test names describe expected behavior from user perspective
- One test verifies one behavior

Ultra-compressed communication mode. Cuts token usage ~75% by speaking like caveman while keeping full technical accuracy. Supports intensity levels: lite, full (default), ultra, wenyan-lite, wenyan-full, wenyan-ultra. Use when user says "caveman mode", "talk like caveman", "use caveman", "less tokens", "be brief", or invokes /caveman. Also auto-triggers when token efficiency is requested.
Adversarial multi-agent planning skill. Self-orchestrates 5 hostile category members (unspecified-low, unspecified-high, deep, ultrabrain, artistry) via team-mode for ruthless cross-critique debate, distills only the defensible insights, then MANDATORILY hands the distilled insight bundle to the `plan` agent for executable plan formalization. Use when planning needs maximum rigor and surfacing of weak assumptions, blind spots, and over-engineering. Triggers: 'hyperplan', 'hpp', '/hyperplan', ...
Routes multi-tool workflows through MCP servers for large datasets and pipelines. Use when Bash tool overhead is limiting throughput on data-heavy tasks.
**Complete production-ready guide for Google Gemini embeddings API** This skill provides comprehensive coverage of the `gemini-embedding-001` model for generating text embeddings, including SDK usage, REST API patterns, batch processing, RAG integration with Cloudflare Vectorize, and advanced use cases like semantic search and document clustering. ---
Recovers prior coding-agent session context by running `catchup <agent> --since-compact`, which extracts a clean summary of a previous Codex, Claude Code, Antigravity, OpenCode, or Pi Agent session. Use when the user says "catch up", "what did the last session do", "get me up to speed", "I switched agents", or asks to recover/summarize a previous session before continuing. Do NOT use for the current conversation, git history, or any non-agent log.
